' 4 Claims.

This invention relates to the art of 'manufacturing synthetic thread and'is a continuation in part of my copending application Serial No. 744,885 filed April 30, 1947, now Patent No. 2,616,156, and entitled Apparatus for Manufacture of Thread.

The apparatus shown in the application referred to includes a thread storing and advancing reel, means for delivering various treating liquids to the filament as it passes through various zones on the reel, and wiping means for preventing or minimizing intermingling of said liquids on the reel and for removing the partly spent liquids, in a segregated manner, from the reel to corresponding points of reclamation or disposal.

The present application is directed to the improved wiping means.

In the accompanying drawings:

Fig. 1 is a view partly in longitudinal vertical section and partly in elevation, diagrammatically illustrating a thread storing and advancing reel to which the improved wiping means is applied.

Fig. 2 is a diagrammatic sectional view on line 2-2 on Fi 1.

Figs. 3, 4 and 5 are fragmentary views showing details of construction.

Fig. 6 is a top plan view of the wiping means the same being shown detached.

The thread advancing reel shown in Figs. 1 and 2 includes a plurality of rolls RI, R2, R3, R4, R15, R6, R! and R8 the opposite reduced ends 10 and H of which are journalled in self aligning bearings l2 and !3 which are carried by end plates l4 and it. The end plate I8 is rotately secured to a center post I 8 by means of pins P which engage arcuate slots, not shown, which are formed in center post IS. The center post IS, in turn, is rigidly carried by end plate I4 which is mounted on any suitable frame or support 2!]. The ends It of the rolls are provided with gears 22 which mesh with a central gear 24, driven by a motor M, whereby the rolls Rl to R8 are rotated about their respective axes. By rotating the end plate I6 relative to the center post Hi, the axes of the rolls are skewed relative to the axis of post l8 as shown at 25 in Fig. 2, whereby, when the end of a filament 28 is wound about the right hand end of the reel, as shown in Fig. 1, the filament will move in the form of a helix the convolutions of which circumscribe all of the rolls, from the right to the left hand end of the reel.

In order to treat an already manufactured thread, or to complete the regeneration of a freshly coagulated synthetic filament, various treating liquids, from pipes Pl, P2, P3, P4 and P5, are brought to bear on the filament as it to the junctions of adjacent zones.

a moves through zones Zl, Z2, Z3, Z4 and Z5 on the uppermost roll RI. The filament is dried, by

structure thus far described forms no part of the present invention.

The liquids used in treating the filament are necessarily supplied in quantities exceeding the absorption and carrying capacity of the filament. For best results, it is desirable that the intermingling of the various liquids be prevented or minimized on the reel and that the excess liquids be removed separately to separate points of disposal or of reclamation.

To this end, I have provided an elongated trough 30 which is divided by wipers 32, 33, 34, 35 and 36 into compartments Cl, 02, C3, C4 and C5 which correspond to zones Zl to Z5 and pipes PI to P5, The wipers 32 to 33 are arcuate in cross section so as to fit against the arcuate surface of the roll RI, as shown in Fig. 2, and are made of rubber, felt, plastic or any other desired material which will not scratch the roll and which will wear out faster than the roll. As will be seen from Figs. 1 and 2, the trough 30 is so positioned that the partitions 32 to 36 will abut the under, or inner surface of roll'Rl at points corresponding In other words, partition 33 abuts the roll atthe junction of zones Zl and Z2 and the partition 34 abuts the junction of zones 22 and 23 and so on. Therefore liquid dripping off the roll, or wiped off the roll by partitions will fall into the corresponding compartments. Each compartment is provided with a drain 38 leading to a point of reclamation or disposal, not shown.

By constantly wiping the underside of the roll at the junctions of adjacent rolls, the movement of liquid from one zone to an adjacent zone is greatly reduced. For example, by constantly wiping the underside of the roll at the junction of zone Zl and Z2, some of the liquid carried by the filament convolution leaving 2! will be taken up by the relatively dry wiped area on the roll so that, by the time said convolution has traversed the wiped area on the roll, it will hav lost a large amount of the liquid which the filament convolution would have carried from zone Zl to zone Z2 in the absence of wipers 32 to 36. It will be noted that the thickness of the wipers is made such as to wipe a zone on the roll wide enough to effect removal of most of the liquid carried by the filament convolutions by the time such convolution has traversed said zone.

In order to insure adequate contact between the wipers and the underside of the roll, and to compensate for wear, the trough carrying the wipers is adjustable relative to the roll. As shown in Figs. 1, 3, 4 and 5, the trough is carried by lugs 40 in which are formed elongated slots 42 for receiving bolts 44 which also pass through holes 46 in lugs 48 formed on or carried by collar or bracket 50 suitably mounted on center post I8 as best shown in Fig. 2. As the wipers wear out, the bolts 46 are loosened, the trough is moved from left to right as viewed in Fig. 1 until the Wipers contact the roll with the desired pressure, and the bolts are again tightened. By this arrangement, the pressure of the wipers against the rolls can be regulated and the useful life of the wipers is increased.

The right hand side of the trough, as viewed in Fig. 2, is provided with an elongated wiperv 52 which extends longitudinally of the roll and is adapted to wipe the entire surface of zone Z5 so as to remove as much liquid from the filament as possible prior to the entry of the filament into the drying zone Z6.

What I claim is:

1. For use in connection with a thread storing and advancing device of a type which includes at least one roll adapted to receive the thread, and 25 ,53

means for delivering various liquids to said thread as it moves through various zones on said roll, an elongated trough, means mounting said trough below said roll, spaced, transversely disposed wipers dividing said trough into separate compartments and abutting the underside of said roll, and separate drains leading from said compartments.

2. The structure recited in claim 1 together with means for adjustably mounting said trough relative to said roll to vary the pressure with g which said wipers contact said roll.
